Abstract
Disclosed is a cylindrical housing mounted within a frame for rotation about its vertical, central, longitudinal axis. A chordal wall divides the cylinder into chordal segments and diametrically opposite access openings in the cylinder sidewall give access to each of the segments. A tray diametrically movable in one segment is controlled by a handle extending into the other segment. Sealing members prevent air leakage between the frame and the cylinder for all rotative positions of the cylinder within the frame.
